WILLIAM L. BLIss, OF NIAGARA FALLS, NewA YORK, AssIGNoR, 'BY MESNE ASSIGN- MENTS, To u. s. LIGHT & HEAT CORPORATION, or NIAGARA CORPORATION OF NEW YORY I serais.

i o i??? whom t may concern:

rBe known that-I, XVILLIAM L. Brass, a citizen of the United States, residingat Ni.- agara Falls, in the county of Niagara and State ol" New York, have invented new and 4.useful lmproveinents in Lubricating' `De- '.vices, of which jooncise, and exact description, reference being had to the accompanying drawing, `torming a part of this slieciication.

the following is a full, clear,

My invention rel atcs to lubricating? dericos, i l lt niore particularly relates to lubricating devices of the type described in my prior application, Serial. No. 572,489, filed July 18th, 1910, in which a. lubricating chain and ring are employed toconvey the oil from an oil well to a rotating shaft.

ihe object of my invention is to provide an impl-med liibricating` device. .A further ebp-et oic nfiy `inveijition is to provide an 1mprofed lubricating device in which the oil is'iedto .the part to be lubricated regardless of the speed at which this part moves.

Otherobjects .and advantages will hereinafter appear.

Y In the accom .an ino" drawines have. in 1 1 b h order to illustrate the principle o my 1nven- Y may be used in'various tion, shownone torni which it may assume in` practice. My invention is not, however, in any Way limited to this specilic forni but i other forms and various other relations.

, ln the drawings Figure 1 shows a sectional view of this device in position in a suitable casing'. ,n 2 shows a longitudinal sectionalview on the line 242 of Fig. 1.

Fig. 3 shows a detail view of the oil ring'.

ln these views I have shown my iin proved lubricating device mounted upon a rotatable shaft 1 and inclosed in a suitable casing 2 having an oil "Well 3 at the bottom, and a suitable oil vinlet lv at one side of the aune. The shatt 1 extends transversely openings 5 in the Opposite ends of s easing 2 a Town in Fig. 2. and is provi'. d with a suitable sleeve-like bearing 6. lfhis bearing has an upper cutaway portion the saine Width as a 'vertically extending; chamber 8 in the casing u llowever, the cutaway portion 7 does not extend around the entire hearing 6, but is only semi-cylindrical in section las Specification of Letters Patent.

`clined or flared from the tread as chamber 3 yand the chain 13 .TJUBRICATING DEVICLn.

shown in Figa 1, .andV is Aso the"lo\ver half of the `bearing' passes Patented Apr. 3, 1917.. Application filed May 3, 191:1.l Serial No. 624,82

arranged thatA through the chamber 8 and houses thev lower half ot the shaft Looscly inounted upon the periphery of the shaft 1 within the chamberl 8 is an oil ring- 9. This oil ring 9 is of a larger dialneter than. the diameter' of adapted to be suspended top surface of the shaft as shown in Fig.' 1. `As shown in Fig. 3 this ring 9 hasa cylindrical slotted treadlO. The slots 1'1 in this vtread are preferablyfarranged gend to end and extend at intervals around thdperiphery of the tread 10. They may however, as# suine different forms. At the sides ofthe tread 10, the Width of which is a trilelless `the shaft and is loosely from the.

than the Width of the chamber 8, this tread is provided With annulardlanges 12. angesarepreferably slightly outwardly inf' shown in Fig'.

3. When placed in position Onthe These shaft, l preferably so arrange the oil ring f i 9 that the lower edges of the flanges 12 dip Within the oil in the oil well 3 so that when' the oil ring 9 is rotated by the action of the shaft, a certain amount of oil Will bepcked l"up by these flanges.

Upon the tread 10, between theA flanges 12 and 'over the slots 11, Ipreferablv hang a` chain 13. This chain 13 has its ends connected to-each other and is adapted'to act as an endless conveyor for the oil. lt is ot such a length that it extends` down into the Oil well 3 as illustrated in Fig. 1, When hung loosely over thetread 10 ol the oil ringv i). This chain 13 is preferably of the construction illustrated in Fig. 2, and consists of a dhain ci. in which the links 14 are of substantially Ushape as shown in Fig. 2 and are provided with the hooked ends 15 which engage the U-shaped portion of the next link.

l/Vhenthe parts are in the position shown in Fig. 2, the flanges. 12 of the oil ring extend over quite close to the Walls of the lies flat upon the tread l0 of the oil ring' over the slots 11, while the lower end of this chain 13 extends vertically downward into the oil Well 3. Thus it is seen that when the shaft 1 is rotated7 the oil in thevvell 3 will' be picked up, partly by the chain 13 and partly by the what is known as the ladder type, f

Q upper side walls of the .chamber 8, and then loWdoWn these walls along thc outside of :the anges 12.130 the shaft 1.. The oil' picked one form which my invention may assume 1n practice, my inventionitself, however, is

in nowise .limited to this'specific form and may assume various other forms` and be used in various other relations, all of which fall within thelscope and forethought of my 1 up by the chain 13 will', however, remain present invention.

upon thechain'as the chain traye'ls with the 9,., and will. pass down through the cli-am to the slots 11 in the tread of the ring Vand' through these slots ll'will' pass to the surface of the shaftl l'. The lubricant which f What I claim as new and desire to secure byLetters Patent of the United States is :e 1:` In combination, a rotatable shaft, a separable externally flanged oil ring loosely mounted onsaid shaft, the periphery of said is supplied to the'shaft 1 Will tend to creep` ring between the flanges being provided along the shaft. In `order to. prevent it frompassing off of theend of thesame, I preferably provide the shaft 1 Witlroue or more slings 16 at one or both of its ends,

abutting against the ends of Athe bearings 6.

These slings are preferably provided with beveled -edges 17 and are arranged' adjacent a collar 18 on the shaft. Both theslingsl and the collar 18 arc preferably located in a` -suitablelchainber 1S) in; the casing 2, communicating with `the oil Well 3 through a channel 20.- When the o"il seeps out along the` shaft to the iange 17, it is thrown olf of these iianges by centrifugal action against the walls of the chamber 19, and is returned to the oil well S throughthe channel 20.

By my improved construction I have prol vided a lubricatingl device which isI adapted to lubricate shafts which rotate at lhigh speed since, due to the provision of ,the slots in theoil ringT the lubricant may readily find its way to these shafts andv is not preventedr from reaching lthe same by the cen trifugal action. due to the highfspeed at which the parts are rotated, whichY has heretofore tended to throw it oil' of the oil ring before it could pass through the` same to the shaft. Further7 my improved construction may be very compactlv assembled upon a shaft and is .of such rugged construction that it is capable ol long use-iu service without any particular attention other than to occasionally supply more oil Ato vthe oil well. lilhilc I have in this application described which said flanges are arranged to rotate, ay

chain loosely hung upon said slottedtread, and means for directing -to the shaft the oil picked up by the flanges in passing through said oil well and thrown off ofthe same by centrifugal action and Said elongated slots vserving to convey the oil 'picked upv by said chainto the shaft at all. speeds of rotation of the shaft."

2. In combination, an oil ring having flaring flanges the periphery of said ring between the flanges being slottedthe slots extending substantially around the entire circumference, a shaft extending through said ring, .said ring bearing directly on said shaft and adapted to be driven frictionally thereby, an oil receptacle into which said ring is arranged to dip, a chain loosely hung upon the tread ot' said ring andextending downward into the oil well, and meansfor directing` to the shaftjg-the oil picked up by reet the oil picket up by said chain to said shaft at all speeds oi rbtation of the shaft.

In witness whoreoil, I have hereunto subscribed my naine-fin the presence ot'two wit vvnesses.
